kopano-cachestat not working

Hi, I’m using Kopano 8.7.5 (UCS integration). Upgraded from 8.7.1. Since upgrade, monitoring by a self-written check_mk plugin does not return any data.
Analyzed it and found that check_mk agent clears locale data on invocation:

returns localized strings (the server is set up in de_DE.UTF-8 locale) even in the absence of LANG, and LC_ALL=C. I would propose stripping the third column from the query, given that it is not processed in any way:

for row in table.rows():
name, value, _ = row

(and the ‘_’ variable not used anywhere in the script). With the proposed changes, the script starts working again under the given environment.
